Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed March 29, 1920. Serial No. sea r71.

To all whom/it may concern:

Be itknown that I, GEORGE P. YOUNG, a citizen of the United States, andresiding at Cincinnati, in the county of Hamilton and State of Ohio,have invented a new and useful Improvement in Elevator- OilingMechanism, of which the following specification is a full disclosure.

My invention relates to a guide lubricator for elevators. Y

The object of the invention is to provide a stationary sight feedlubricator for do livering a properly alined flow of oil to the medialportions of the vertical guides of an elevator, and to deliver the sameto the bearing surfaces of the elevator shoe, the latter carrying wipersto remove superfluous oil and to distribute the oil film uniformlythroughout the vertical length of the guide.

Heretofore, the sight feed cup has been placed on top of the elevator orupon the counter-weight, where it is difficult of access for the properadjustment of the oil flow, the result being that the said flow isgenerally incorrect and that it is generally made too great because ofthe difficulty of adjustment, and as a result oil collects on top of theelevator.

The features of the invention are more fully set forth in thedescription of the accompanying drawings, forming apart of thisspecification, in which:

T Figure 1 is a fragmentary elevation. of an elevator guide, showing myimproved lubricator attached thereto. 7

Fig. 2 is a plan section of one of the guides, showing the arrangementof the oil passages therein.

Fig. 3 is a fragmentary front elevation of a guide showing oil grooves.

Fig. 4; is a front elevation, showing the relation of the wipers to theguide and to the oil passages therein.

Fig. 5 is a side elevation of the structure shown in Fig. 4.

Fig. 6 is a plan section through the rail shown in Fig. 4.

Without showing more of the apparatus than is necessary to disclose theinvention, 1 represents the roof of the shaft, 2 the vertical guide-wayto be lubricated. 3 the elevator car, 4 the'car shoe having a three-facebearing on the guide, and 5 represents spring-pressed wipers, (see Figs.i and 5), secured to the upper end of the shoe on .opposite sides of theguide, the wiping members'being suitable oildistributing pads or blocks.1

At the upper end of the shaft is the sightfeed oil cup 6, having theusual drop adjustment into the upper end of a vertical conduit 7, placedat'the rear and adjacent the guide and preferably terminating atapproximately the medial portion of the guide. At the lower end is anelbow 8 communicating with the horizontal ducts 9, the said ducts inturn communicating with the distributing ducts 10, in the bearingsurfaces of the guide. I

The cup being stationary and accessible, can be easily adjusted to keepthe oil flow constant and in proper quantity, avoiding waste, the dangerof oil accumulation on the elevator, and at the same time enabling a farmore uniform and efficient distribution of the oil to all portions ofthe guide bearing surfaces throughout theirlength.

In order to additionally guard against the accumulation of oiloverflowing into the top of the car, I preferably form the top of theshoe with the chamfered portions 11, which act to wipe the oil inwardlytoward the guide surfaces, and further function to flow any superfluousoil downwardly and inwardly instead of outwardly and downwardly on theouter surfaces of the shoe, from which oil would drop onto the top ofthe car.

Not only is the adjustment made and maintained properly and the oil flowefficiently distributed, but the oil is thereby definitely andpositively confined to the shoe and to the guide surfaces to belubricated.

This invention though simple, produces increased economy, efficiency,convenience of adjustment and constancy, also constitutes an addedelement of safety and lessens the gaged with said rail and wiper carriedby said car engaging said rail bearing surfaces.

2. An apparatus for elevator lubrication comprising a stationary sightfeed drop lubricator at the top of an elevator shaft, a vertical guidehaving bearing surfaces, a shoe on the car sliding on the guide andhaving wipers contacting the bearing surfaces, a vertical conduitdropping from the lubricator cup to an intermediate portion of thevertical guide, a conduit transversely through the guide, communicatingwith said vertical conduit and having terminal ducts delivering to thebearing surfaces of said guide, and means preventing the oilaccumulation upon the shoe.

3. An apparatus for elevator lubrication comprising a stationary sightfeed drop lubricator at the top of an elevator shaft, 2.

vertical guide having bearing surfaces, a shoe on the car sliding on theguide and having wipers contacting the bearing surfaces,

a vertical conduit dropping from the lubricator cup to an intermediateportion of the vertical guide, a conduit transversely through the guide,communicating with said vertical conduit, having terminal ducts delivering to the bearing surfaces of said guide, and the upper surface ofthe shoe be ing chamfered to drain superfluous oil inwardly toward thebearing surfaces.

' In Witness whereof, I hereunto subscribe my name, as attested by thetwo subscribing Witnesses.
